In order to recover printing after a failure during a tool change we need to know the toolhead position before starting the tool change. This change will save the position at the start of the tool change and then provides a macro (`RESTORE_CHANGE_TOOL_POS`) that can be invoked at the end of your `RESUME` macro to restore that position.
Can help with some variance in the filament tip potentially blocking. Recommend increasing the park distance if using tip forming.

These changes should help with less than ideal tool changes. In particular, I am testing on a setup without a cutter, so it relies on tip forming. The primary issue with tip forming is that the tips are inconsistent due to differences in temp, material, and whether you are looking at your printer funny. Because tips are inconsistent, it makes tool changes less reliable. These changes help with that in a few ways:
RESUMEmacro to callRESTORE_CHANGE_TOOL_POS.With these changes I've successfully been able to do a test print doing 10 swaps and when it inevitably fails to do a tool change, I was able to recover and resume successfully.
